I have 2 balnced 7-7-7 fertilizer of flowers and flortis companies. It's instructions say to put 5cc/ml to 2 liters. Now start using hydroton semi hydroponic how should I dilute the fertilize what ppm and ph should I look for achieving thank you all.

2.5 ml/L of a 7-7-7 is about 50 ppm N, which is a good level for feeding about every 5 days. Cut that if you feed more frequently, increase it, if less.

As long as the solution is between 5 and 7, or even a fraction outside of that range, it'll be fine.

0.54 teaspoons is 2.66 mL so Ray was correct when he rounded to 2.5 mL per gallon.

Yes but per gallon is 2.5ml/4l not for 1l so I just going to dilute 2.5ml for 3.8 liter

Its messy when we mix metric and non-metric measurements, but my reverse osmosis water gets stored in gallon jugs but I add various things in mL.

If you want to go all metric, you would add the 0.7 mL to each liter.

Thank you ray for your quick response. Another question that I have I read all your website. Is it matter if I repot orchid while at 19°c min before the spring or it will affect the adoption period or success. In the summer it's really hot 30°c should I make deeper resivor or stay at 1 inch?
Thank you in advance!

I cannot tell you whether or not to make he changeover now or later. What you have to consider is that, for the best result, new roots should be emerging from the base of the plant when you do.

No, don't change the depth of the reservoir. That has nothing to do with your conditions; it has to do with the depth of the pot, and how far the roots penetrate down into the medium.
